COIN-CONTROLLED VENDING MACHINE.

Specification of Letters Patent.

Patented May 2, 1922.

Application filed November 13, 1917. Serial No. 201,739.

To all whom it may concern Be it known that I, FRANCIS M. CAsE, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Coin-Controlled Vending Machines, of which the following is a specification.

This invention relates to coin controlled vending machines, and particularly to machines:f0r vending small spherical articles, such a balls or marbles of gum, confections,

or any other materials, or other small artition, the delivery or ejectment of the proper number of balls or loads corresponding to the value of the inserted coin.

A further object of the invention is to provide a machine of this kind in which the balls areejected by a stroke or movement of the operating device in one direction, the machine being so arranged that upon any motion of the operating device in the retracting direction further ejectment of balls is prevented until another coin is inserted into the machine. a

A further object of the invention is to safeguard the machine against improper manipulation by tilting it or turning it to an unnatural position, so as to prevent unautho'rized persons from thereby obtaining balls from the machine without the insertion of the proper coin.

A further object of the invention is to provide a machine of this kind which cannot be tampered with by interlopers and which returns to the operator slugs or tokens inserted as a substitute for lawful coins.

A further object of the invention is to i provide a machine of this kind in which the balls may be held in a large transparent reservoir likely to attract custom and are agi- Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

The inventioncomprises the vending machine hereinafter described and claimed.

In the drawings, which represent one embodiment of the invention, Fig. 1 is a front elevation, partly broken out to expose the lnteriorparts; Fig. 2 is a sectional elevation on the hne 2-2 Fig. 1; Fig. 3 is a sectional plan view on the line 33, Fig. 2, the reservoir being omitted; Fig. 4 is a sectional plan View on the line 44, broken out to expose underlying parts; Fig. 5 1s a sectional plan view on substantially the llne 55, Fig. 2; Fig. 6 is a detail sectional elevation, on a larger scale, on substantlally the line 6-6, Fig. 5, the coin carrying disc being omitted; Fig. 7 illustrates a development of the circular controlling rack and parts operating therewith, the parts being shown after the ejectment of a single ball; Flg. 8 is a similar view, illustrating another position of the parts; and

Fig. 9 is a detail view, illustrating the operation of a safety appliance.

The apparatus shown in the drawings comprises a hollow casing l suitably shaped to contain the operating mechanism and forming a solid base or edestal for the machine. Its top is provic led with a circular shoulder 2 forming a seat for the rim of the open bottom mouth of the reservoir 3 for containing the balls to be ejected. This reservoir may be of any suitable shape or material, and isshown as a-large hollow glass sphere. The upper end of the reservoir is provided with a rimmed opening 4 on which rests a ring 5 carrying a cross member 6 provided with an opening to receive a long bolt 7 Whose lower end may be-screwed into an opening in a substantially horizontal wall 8 partially closing the top of the base casting 1. Ring 5 is provided at one side with a perforated ear 9 and its inner periphery is provided with a pair of oppositely disposed vertical slots or recesses 10 through which may be passed the hook members 11 on the under face of a cover 12 having a perforated car 13 at one'side. By inserting the hook members 11 through the recesses 10 the cover may be turned to the position shown in Fig. 2 and the hasp .of a lock passed through the openings in the ears 9 and 13. This arrangement locks the receptacle closed and prevents it from being removed from the pedestal except by an authorized person.

The lower portion of the pedestal serves as a reservoir to receive the coins introduced into the device, after utilization of said coins to actuate the control devices. Its bottom opening is closed by a door or cover 14 provided at one side with one or several tongues 15, two being shown, adapted to enter openings in the wall of the casing. At its opposite side the cover 14 i slotted radially to receive a vertical rib 16 on the inner wall of the casing. Said rib is provided with an opening 17 to receive the hasp of a lock 18. in addition to which the cover may be arched as at 19 to provide alock cavity 20.

The wall 8 at the upper end of the casing is of peculiar shape, being inclined from front to rear, as shown in Fig. 2, and having its rear portion cut away to form a circumferentially extending opening or gate 21, as shown in Fig. 3, thereby exposing through said opening the ball transfer device 22. Opening 21 is slightly wider, in .a radial direction, than the diameter of the largest ball to be delivered. Consequently the balls in the reservoir 3 always tend to roll from the wall into and through the opening or gate'21 and down upon or into the ball transfer device. This latter device is provided with a, central hub 23 rotatably' mounted upon a stub shaft 24 screwed into a cross wall 25 attached by screws 26 to lugs or brackets on the casing. As shown, the lower portion of the central hub member. 23 surrounds a reduced portion of a circular rack controlling member 27, hereinafter to be referred to. These parts, to wit, the ball transfer device and the controlling member 27 might be integral with each other, but

for easeof construction and for purposes of illustration have been shown as separate members connected by the pin 31, so as to rotate together. The outer wall of member 23 extends upwardly and then outwardly and has a horizontal flange 28 provided in its periphery with a series of circumferentially spaced recesses or pockets 29, five being shown, and which recesses have curved vertical walls 30, as shown in Fig. 2. Each recess islarge enough to receive a single ball where large balls are to be discharged in-' dividually or a single load of smaller articles like nuts, and the Walls 30 prevent the balls or other articles from escaping laterally from said recesses after entering the same, except as hereinafter noted.

Figs, 3, 4 and 5 all show the parts in position ready to receive a coin. Upon the insertion of a coin into the machine the operating handle is manipulated to cause rotation of the ball transfer device 22 in the direction indicated by the arrow A, Fig. 3, thereby causing the pockets or recesses 29 to 'cup 39 having its front wall 40 extending upwardly to form a positive stop, for the pass in turn beneath the opening) or gate 21, 1n wall 8, each receiving its own all or load. To insure the filling of all pockets and prevent the balls from arching or jamming in the reservoir, which might otherwise occur, suitable means is preferably provided for agitating the balls. For this purpose the transfer device 22 is provided with one or a plurality of upwardly .projecting pins 32, (one being shown) extending up sufficiently far to engage and move the balls. Wall 8 is also provided with a narrow slot 33 to permit said pins to pass under the rear portion of the same when the member 22 is rotated.

Suitable means is also provided for preventing the balls or loads from escaping radially from pockets 29 until they in turn reach the discharge opening or outlet. This means comprises a depending annular flange or wall 34 of the casing, which lies closely adjacent the periphery of member 22 and which may extend down to a plate 35, as shown.

While being moved around with the member 22 the balls rest and roll upon the horizontal plate or floor 35 suitably attached to the casing. Beyond the far end of the opening 21 in the wall 8 floor 35 is provided with a recess 36 forming an outlet leading into a trough or channel 37, which slants downwardly toward the front portion of the casing and leads to a door or opening 38 therein. On the outside of the casing, in front of said opening, is a ball receiver or balls, and having its sidewalls cut down wardly, as at 41, to enable the thumb and finger to readily grasp the opposite sides of the ball and lift it from the cup. If a nickel has been inserted in the machine the operating mechanism allows member 22 to rotate far enough to discharge five balls into the trough 37. The outer one only of said balls is exposed at the cup, the remaining balls being piled upon the first in a column, so that the operator removes them one by one.

The rotating mechanism for the ball transfer device 22 is a horizontal shaft 42 journalled in suitable bearings in the wall 25 and provided with a bevel gear 43 meshing with a bevel gear 44 on the bottom of member 27. This shaft 42 extends to the outside of the casing where it is provided with an operating handle 45. Rotation-of said handle in the 'clockwise' direction, Fig. 1, advances member 22 to discharge a ball or balls, while rotation of said handle in the opposite or retracting direction restores the apparatus to condition for another operation.

The coin for releasing the controlling apparatus is inserted into a round opening 46 at the front of the casing. It rolls down over the end of an inclined magnet 47 whose lower end is above the outer end of the chan- 130 nel 37. Consequently a slug of steel, iron or other magnetic material will cling to and roll down the magnet and be discharged into the cup 39. A proper coin, whether it be a penny or a nickel, drops vertically through a channel to a recess or seat 48 in a coin carrying disc 49 fixed to rotate with the shaft '42. Fig. 1 shows a coin in this position.

At one side of and slightly above the shaft 42, is located a stationary pawl shaft 50 parallel with the shaft 42 and secured in suitable bracket-s or lugs 51 on the wall 25. 011 said shaft is rotatably mounted the hub of a. value controlling or governing member 52 provided with one arm having a forwardly projecting tongue 53 lying opposite the periphery of the disc 49, and a second arm 54 having a lateral extension 55 (Fig. 5) lying above the periphery of the circular controlling rack 27. This arm 54 also lies directly beneath a gravity pawl 56 mounted to swing loosely in a vertical plane upon a post 57 carried by the wall 25. The toe portion 58 of said pawl also lies over the circular controlling rack 27 and extends inwardly beyond the projection 55 to co-operate with the teeth of said rack, as will more fully appear. The hub of the value controlling member 52 is also provided with-a depending third arm 59 passing through an opening in the wall 25 and lying opposite or in the plane of rotation of a co-operating arm 60 on the shaft 42.

Member 60 is not keyed to rotate continuously with its shaft 42 but is connected thereto by a suitable friction clutch or device. As shown, the arm 60' has a sleeve portion 61 rotatable on shaft 42 and pressed endwise against the hub of the disc 49. by a light pressure spring 62 surrounding the shaft 42 and lying between sleeve 61 and a cross pin 63 on the shaft 42, as shown in Fig. 2. The spring therefore rotates with the shaft, at times carrying with it the arm 60, as will appear;

' A similar pressure spring 64 surrounds the shaft 50 and is located between one of the it from turning. This arrangement prevents any tendency to twist the coil which might thereby produce a reacting effect upon the member 52 and turn it slightly backward after a coin passes its arm 53 and, thereby aifect its otherwise accurate setting.

The circular controlling rack 27 has a plain outer peripheral portion 65 on which the portion 55 of the value controlling member can ride, and adjacent thereto a cirportion 68 located at a slightly higher level,

, whose angular value in the circle is equal to substantially the width of a single pocket 29, a longer toothed portion 69, located at a still higher level and whose angular value in the circle is equal to the; width of four of the pockets 29, and finally a stop 70 which extends up beyond the higher teeth69.

Figs. 1 and 8 show the parts the position just after inserting a coin a, which has dropped to its position in its seat 48 in the disc 49. The tongue 53 of the value controllin member is in contact with the perip cry of said disc and the arm 54 of said member either rides upon or is closely adj acent the plain peripheral portion 65 of the circular rack member. Pawl 56 rests upon arm 54 and its extreme end is below the level of the lower set of teeth 68. The operating handle 45 is turned in a clockwise direct-ion, Fig. 1, thereby rotating the circular rack in a counter-clockwise direction, Fig. 5. The rotation of said shaft also carries with it in a clockwise direction, Fig. 6, the arm 60, moving said arm away from the arm 59 until it strikes the abutment 71 at the end of the opening or slot in the plate 25 through which said arm. projects. During further rotation of the shaft in the clockwise direction arm 60 remains stationary. Rotation of said shaft also carries the coin in thedisc 49 past the tongue 53 of the value controlling member. The cavity or seat 48 inthe disc 49 is shallower or of less depth than the diameter of the smallest coin intended to be used with the machine. In the particular machine shown, adapted for use with pennies and nickels. this seat is shallower than the diameter of the penny, which therefor projects slightly beyond the periphery of the disc49. As said penny moves past the tongue 53, it pushes said tongue out of the way, turning the member 52 in a clock-Wise direction, Figs. 6, 7, and 8, and setting said member in a position corresponding to the coin, and in which position it is held by the spring 64. If a penny is in the seat said memiber will he turned just far enough to raise the end of the pawl 56 slightly above the upper ends of the teeth of the lower rack section 68. Consequently the shaft 42 can be rotated until the vertical shoulder 72 between the teeth 68 and 69 abuts the end of awl, as shown in Fig. 7, thereby prethe venting any further motion of the operating handle in the clockwise direction. When this position is reached the ball transfer device 22 has rotated just far enough to bring the first one of the pockets 29 over the outlet 36 to the discharge chute 37, and a single ball is therefore ejected from the machine into the cup 39. The mechanism cannot be. turned further in the ejecting direction until it has been {Moved fully back to its initial position and another coin inserted in the coin receiving disc.

If a nickel is inserted into the disc, said nickel in passing the value controlling member 52 turns and sets the same sufficiently to raise the end of the pawl 56 slightly above the upper end of the teeth 69. Consequently the operating handle can be turned a full. stroke in the clockwise direction until the stop abuts the pawl, as shown in Fig. 6. This motion brings each one of the five pockets in member 22 in order over the exit 36, so that five balls in order are discharged into said pocket. A portion of the wall 8, indicated at 73, Fig. 3, lies over the exit 36 and prevents any balls from leaving the reservoir except as they may be conveyed to the exit by the pockets 29.

After the coins pass the member 52 they drop from the disc to the bottom of the casing, as will be readily understood. Let us now assume the parts-in either of the positions shown in Figs. 6 and 7, that is, after an ejecting stroke to' discharge either five balls or one ball. Before the machine can be again operated the parts must be restored to their original position, shown in Fig. 8, by rotation of the operating handle 45 in the counter-clockwise direction Fig. 1. The first backward motion of said handle, through the friction spring 62 turns the arm 60 in a counter clockwise direction, Figs. 6 and 7, and as the camming effect of arm 60 imparted to it by friction through the spring 62 is greater than the frictional resistance of the spring 64 the first rotation of the operating lever causes the arm 60 to engage arm 59 and turn the value controlling member 52 in the backward direction until it reaches the position shown in Fig. 8. This motion leaves the gravity pawl 56 resting loosely upon the rack teeth, so that during the backward rotation of the circular rack member the pawl drags over the teeth, thereby preventing any rotation of the operating handle in the ejecting direction until the value controlling member has been again lifted and set to elevate and positively hold the awlv out of engagement with the rack teet This arrangement, therefore, requires the operator to completely turn the operating handle in the backward direction to initial position.

It will, of course, be understood that if the operating handle is turned from the initial position in the ejecting direction without inserting a proper coin the ball transfer device will be rotated only until the pawl strikes the abutment of shoulder 72 in ad- Vance of the lower set of teeth 68, thereby stopping the transfer device before a ball is ejected from the machine. Furthermore, if a proper coin is inserted into the machine, said coin cannot reach the coin receiving reservoir in the bottom of the machine except by passing and operating the value controlling member 52. For example, if a coin is inserted into the opening 46 before the operating handle has been retracted, said coin will lodge upon a plain portion of the periphery of the disc 49, remaining there until the operating handle is fully retracted, when it will enter its proper seat in the disc ready for actuation of the value controlling member when the. handle is turned in the ejecting direction.

Suitable means is also provided for preventing unauthorized manipulation of the machine by bodily tilting or turning the entire machine to lie on its left side Fig. 1. Fig. 9 represents the position of the controlling parts when the machine is turned to such a position. Without special provision the pawl 56 in this position would hang down vertically so that its end portion would be out of range of the rack teeth 68 and 69 thereby enabling the operating handle to be rotated freely back and forth, which might discharge balls from the machine if the reservoir were full. To prevent such operation the pawl carries a counter Weight 74 pivoted at 75 to said pawl at a point remote from its pivot 76, so that the heavy portion of the counter weight lies between the pivot 75 and the pivotal connection 76 of the pawl to it post.

Consequently when the machine is tilted to abnormal position, as described, the counterweight drops down to the position shown in Fig. 9 and Wedges in between the pawl and a portion of the wall 35, thereby preventing movement of the pawl away from the blank portion 56 of the circular rack.
